Cells

Explanation:

High-powered microscopes are used in order to see microscopical (extremely small) structures of objects that cannot be seen with a naked eye.

When we look at a leaf, we will see the composition of it and the structural patterns that we couldn't see clearly or at all without a microscope.

Leaves consist of cells and spores (stomata) between the cells. Using a microscope will enable us to see them.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
